Air Pressure Regulators

Precision pressure regulators control air pressures in applications where precise and dependable regulation is required, such as pneumatic instrument circuits, test stands, production checking fixtures, and industrial air gauges.

I/P Transducers

The model 77 current-to-pneumatic transducer is designed specifically for measuring circuits, converts the output of an electronic measuring device to a pneumatic signal.
The model 771 current-to-pneumatic transducer is designed as a cost-effective valve service transducer. The 771 receives an electronic signal, such as the output of a PID control function, and drives a control valve via the transducer until the control function is satisfied.

Flow Controllers & Relays

The model 62 constant differential relays serve as air-flow controllers maintaining a constant air purge for each setting of an integral needle valve.
The model 63 constant differential relays are used in con- junction with an external needle valve to provide constant volume flow rates of liquids or gases over a continuously adjustable range.
The model 66 amplifying and reducing relays are used to in- crease or decrease control-circuit pressure signals.

Air Filter

The instrument air filter is used to remove dirt, oil, water, and other impurities from an instrument-air supply. The highly efficient instrument-air filter uses the principle of coalescence to trap fine particles in a dripwell.
